<h1 class="topictitle1">Restoring FusionCompute VMs</h1>
<div><p>This section describes how to restore a VM that has been backed up to the original location or a new location.</p>
<div class="section"><h4 class="sectiontitle">Context</h4><p>The <span>OceanProtect</span> allows you to restore VMs to the original location or a new location using backup copies, archive copies (restoration to the original location is not supported after a replication copy is archived) or replication copies (data cannot be restored to the original location).</p>
</div>
<div class="section"><h4 class="sectiontitle">Precautions</h4><div class="p">When a VM is being restored, the following configuration items of the VM will not be restored. After the restoration is successful, log in to the FusionCompute management page to manually set the configuration items.<ul><li id="EN-US_TOPIC_0000002164765994__en-us_topic_0000002200007125_li46091916153618">Memory - Hugepage memory</li><li id="EN-US_TOPIC_0000002164765994__en-us_topic_0000002200007125_li230813253365">CPU - Binding information</li><li id="EN-US_TOPIC_0000002164765994__en-us_topic_0000002200007125_li31340281363">VM startup mode - Specify device boot sequence</li><li id="EN-US_TOPIC_0000002164765994__en-us_topic_0000002200007125_li4294930103615">PCI device information</li><li id="EN-US_TOPIC_0000002164765994__en-us_topic_0000002200007125_li19261154573516">GPU resource group parameters</li><li id="EN-US_TOPIC_0000002164765994__en-us_topic_0000002200007125_li89521556121217">NUMA topology adjustment</li><li id="EN-US_TOPIC_0000002164765994__en-us_topic_0000002200007125_li095225631211">CPU/Memory hot add</li></ul>
